As a power generation method with the most mature technology, the most large-scale development conditions and commercial development prospects in the field of new energy, wind power has achieved rapid development. As wind power technology extends from land to ocean, offshore wind power is becoming a focus of development in the new energy sector. Compared with onshore wind farms, offshore wind farms have the advantages of large reserves of wind energy resources, high development efficiency, low environmental pollution, and no occupation of cultivated land. The wind power jacket construction project is the construction project of Jiangsu Xinhantong as the company's economic growth point project and Nantong Ocean Water Construction in 2011. The main construction object is the production of some jackets on the fan jacket foundation structure of Jiangsu Rudong Demonstration Wind Farm. . Difficulties in the manufacture of the jacket: the diameter of the upper end of the main cylinder is 4.2 meters. After the flange welding, the flatness is not more than 3MM, the camber is not allowed, the internal inclination is not more than 1.5mm, the control of the large flange is difficult; the main cylinder is made of 40mm high strength board. The cone is made up of a cone with a taper of 8 degrees, and the cone volume is difficult; the jacket is a connection between the wind tower and the sea sinking pile. Each jacket must be made according to the piled pile data on site, and the precision control It is difficult; the jacket is subjected to the weight of the wind tower, fan cabin and blades after installation, and also needs to bear the moving load of the blades. Therefore, the weld quality of the jacket is strict, and all welds are 100% ultrasonic flaw detection, all T The seam is qualified by radiographic inspection; according to the company's requirements, the project must be organized and standardized by the offshore engineering project management model, and the requirements for the management personnel and management capabilities of the project are strict. Since the beginning of the project in early November, the project has invested 15 million yuan to introduce large-scale CNC coiling machines and welding lines from abroad, with a designed production capacity of 3,500 tons/month. At present, the production of the new Hantong jacket is being carried out in an orderly manner. The technical design of the jacket is carried out by the technical department of Shinhantong. The WPS has passed the approval of the owner and BV ship, and the various process documents and conditions for commencement have been approved by the supervisor. The first two jackets are scheduled to be delivered to the Longyuan Rudong Offshore Wind Farm in mid-September.
In the background of the downturn in the shipbuilding market, wind power jackets as a demonstration product of the new Hantong in the construction of marine steel structures have important strategic significance for the future development of the company.
